CVE-2026-3765 identifies a SQL injection vulnerability in the itsourcecode University Management System version 1.0, located in the /att_single_view.php file. The vulnerability arises from improper sanitization of the 'dt' parameter, which is used in SQL queries without adequate validation or parameterization. This allows a remote attacker to inject malicious SQL code, potentially manipulating the database queries executed by the application. The attack does not require authentication or user interaction, making it easier to exploit remotely. The vulnerability can lead to unauthorized data disclosure, modification, or deletion, impacting the confidentiality, integrity, and availability of the system's data. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). No patches or fixes have been explicitly linked yet, and while no active exploitation in the wild is reported, a public exploit is available, increasing the risk of future attacks. The affected product is primarily used in academic environments, which may contain sensitive student and faculty data, making the vulnerability particularly concerning for educational institutions.

The potential impact of CVE-2026-3765 is significant for organizations using the itsourcecode University Management System 1.0. Successful exploitation can lead to unauthorized access to sensitive academic records, personal information, and administrative data. Attackers could manipulate attendance records, grades, or other critical information, undermining data integrity and trust in the system. Confidentiality breaches could expose personally identifiable information (PII) of students and staff, leading to privacy violations and potential regulatory penalties. Availability may also be affected if attackers execute destructive SQL commands, causing data loss or service disruption. Given the remote and unauthenticated nature of the exploit, attackers can launch attacks at scale, potentially targeting multiple institutions simultaneously. The presence of a public exploit increases the likelihood of opportunistic attacks, especially from less sophisticated threat actors. The impact is amplified in regions where this software is widely deployed and where educational institutions have limited cybersecurity resources.

To mitigate CVE-2026-3765, organizations should immediately review and sanitize all inputs, especially the 'dt' parameter in /att_single_view.php, using strict input validation and allowlisting techniques. Implement parameterized queries or prepared statements to prevent SQL injection attacks effectively. If source code modification is possible, refactor vulnerable code to use secure database access methods. Network-level mitigations include deploying web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the vulnerable parameter. Monitor logs for unusual query patterns or repeated access attempts to /att_single_view.php. Restrict access to the application to trusted IP ranges where feasible. Regularly back up databases and verify backup integrity to enable recovery from potential data corruption or deletion. Stay alert for official patches or updates from itsourcecode and apply them promptly once available. Conduct security awareness training for administrators on recognizing and responding to SQL injection attempts. Finally, consider migrating to updated or alternative university management systems with improved security postures if feasible.
